Tao Li updated HIVE-17422:
--------------------------
Description:
Currently during incremental dump, the non-native/temporary table info is
partially dumped in metadata file and will be ignored later by the repl load.
We can optimize it by moving the check (whether the table should be exported or
not) earlier so that we don't save any info to dump file for such types of
tables. CreateTableHandler already has this optimization, so we just need to
apply similar logic to other scenarios.
The change is to apply the EximUtil.shouldExportTable check to all scenarios
(e.g. alter table) that calls into the common dump method.
